From Duane Hendricks - 4k Laptop & Desktop Reviews - Best 4k Gaming Notebooks - Posted 11-23-2016 (1-17-2017) "Key Points: You need to ask yourself what you need 4K visual display for and understand a fundamental thing: 4K resolution is almost indistinguishable from Full HD resolution on the kinds of small screens that laptops​ ​come with.​ ​So unless you mostly want the 4K graphics for the sake of knowing you have them, even if hardly anyone can distinguish your screen from an HD screen, then go ahead, but you might find yourself a bit underwhelmed by what you see.​

The bottom line is that while 4K laptops create truly, almost impossibly crisp imagery for graphics in native 4K resolution, they aren’t something you really need unless you plan on regularly working with native 4K resolution in terms of graphics and image editing."

Duane Hendricks - PCWorld - The 22 best changes in Windows 10 Insider Preview Build 15002 Posted 1-12-2017 (1-13-2017) "Here is what the article says about scaling. Proper icon scalingOne of the perpetual bugs I notice with Windows 10 is the lack of icon scaling. Sometimes you can un- and re-dock a Surface Book, and everything looks as it should. On other occasions, though, icons become crazily resized, and app windows get thrown out of whack. Build 15002 promises to reconcile this once and for all, and in my limited time with it, it seems to.

If Windows doesn't apply the changes consistently, you may be able to enable what Microsoft calls "high DPI support" by right-clicking on a program's EXE file, opening its properties, and checking "Override high DPI scaling behavior" under the Compatibility tab."
